使用MAQ470GQE和PIC32MZ1024EFH064发现磁铁的角位置

 * @brief Angle6 Click example
 *
 * # Description
 * This example demonstrates the use of Angle 6 Click board by reading and displaying
 * the magnet's angular position in degrees.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration which 
 * sets the rotation direction to clockwise.
 *
 * ## Application Task
 * Reads the magnet's angular position in degrees and displays the results on the USB UART
 * approximately every 100ms.
